To all whom it may concern:

Be it known that I, CYRUS S. Moons, of Ei-ie, in the. county of Erie, and State of Pennsylvania, have invented at new and improved Manufacture or Composition of Matter; and I do hereby declurethe following to be a. full and exact description of the some,

' position of inatter is as follows, to wit:

1 first take ten barrels of the residuum left aft-er refining crude petroleum. To this 1 add one. barrel of benzole, or any of the lighter products of petroleum, or the crude petroleum itself; this is added to reduce the residuum, or tar, to a more fluid consistency. I then bring the mixture to a boiling-heat, for the-purpose of insuring u more perfect chemical action.

-\Vhile at said boiling-heat, I add to theniixture three gallons of alkali, or any alkaline substance of suflficient strength to cleanse and purify the same. I then immediately add three pounds of sultpetre, five pounds o'frock-sult, and fifteen pounds of sulphur. These ingredients, especially the sulphur, serve to make the Inbricant less liable to heat when in use on the journals,

& c., of machinery. lalso add one gallon of ammonia,

the object of which is to keep the oil from congea-ling when reduced to a low temperature.

\Vhut I claim as my invention, und'desire to secure by Letters Patent of the United States, is as follows, to wit:

1. The mode, herein described, of producing u luhricu't-ing-oil from theresiduum left after refining 1M troleurn.
